Car Wash Parking Lot Striping in Forest Grove, Oregon: 2026 Service Guide

Striping a Car Wash Lot in Forest Grove

A car wash lot is all about flow. Cars enter, stack for the tunnel, exit to vacuum bays, and sometimes move on to a detail bay, all in a tight loop that has to keep moving. In Forest Grove, where car washes catch traffic along Pacific Avenue and Highway 47 in the western Tualatin Valley, much of it returning dusty from rural roads or wine-country gravel, clear striping keeps the cycle from snarling and keeps wash water contained.

Cojo Excavation & Asphalt restripes car wash lots throughout Forest Grove and the surrounding Washington County area. Here is what a car wash lot needs, what the work costs, and how the local climate shapes the schedule.

What a Car Wash Lot Needs From Its Striping

Car wash parking is really a directed flow, and the striping is what directs it:

• Vacuum-bay pull-in stalls marked so cars park squarely at each station without crowding the next bay
• Tunnel-entry stacking lanes striped to hold the wait line without backing into the street or the vacuum area
• Detail-bay staging spaces for vehicles waiting on a hand detail or extra service
• An ADA office path giving customers a clear accessible route to the pay station or office
• Drying-apron flow arrows guiding cars from the tunnel exit through the dry-off and vacuum loop
• Reclaim-water trench keep-clear striping and DEQ runoff markings, keeping wash water in its containment path and away from storm drains

The flow arrows and the stacking lane matter most, because a confused entry sequence stalls the whole operation.

What Car Wash Striping Costs

Cojo does not quote a flat rate, since every lot is different. The figures below are the national industry baselines contractors use as a starting reference. Treat them as a budgeting frame, not a quote.

Industry baseline ranges shown below. Actual costs vary with surface condition, paint type, layout complexity, and current market conditions.

Service	Industry Baseline Range
Per-space restriping (existing layout)	$3–$6 per space
Directional arrows	$25–$50 each
ADA-compliant space (complete)	$200–$350 per space
Keep-clear / trench striping (per LF)	$0.30–$0.65
Stencils (STOP, ENTER, etc.)	$30–$75 each
Stacking-lane edge lines (per LF)	$0.20–$0.50

Actual project costs around Forest Grove often run above these baselines, especially when a wash has multiple bays, arrows, and runoff markings. See our parking lot striping cost in Oregon guide for regional pricing.

Why Flow Markings Drive the Number

A car wash has fewer standard parking stalls than most commercial lots but far more directional work: arrows, lane lines, staging zones, and keep-clear striping for the water trench. The ADA route to the office still needs exact dimensions, blue paint, the accessibility symbol, and signage. The volume of arrows and lane markings, not the parking count, often drives the quote, which is why a contractor measures the layout before pricing.

Factors That Affect Your Forest Grove Project

Surface Condition

A car wash lot is wet by design, and constant moisture is hard on both asphalt and paint. Lots with cracking, standing-water spots, or a worn sealcoat need prep first, which adds to the total. Combining the work with a fresh sealcoat helps the lines hold up in a wet environment.

Paint Type and Durability

• Water-based latex — most common and lowest cost, though it wears faster in a constantly wet lot
• Oil-based — better adhesion in damp conditions at a moderate upcharge
• Thermoplastic — premium and most durable, often the best value for the high-wear flow arrows at a wash

Climate and the Tualatin Valley

Forest Grove sits in the western Tualatin Valley near wine country, with damp, mild winters and warm, dry summers. Traffic paint needs a dry surface above 50°F to cure, so the striping season runs late spring through early fall. Booking early in that window helps secure a date.

What a Contractor Can't See Until Work Begins

A careful walk-through still misses some conditions: paint peeling under the top layer, asphalt softened by constant moisture, cracks hidden beneath faded arrows, and an ADA route that no longer meets current standards. Any of these can change the scope once work begins, which is why an on-site assessment beats a price chart.

When to Restripe Your Forest Grove Car Wash Lot

Restripe when arrows and lane lines fade past about 50 percent visibility, when the stacking lane loses definition, when the trench keep-clear markings wear off, or after a compliance notice. A freshly sealcoated lot also needs new lines.
